7722FV Bottom Vision Test

[ktownsend]

I was going through your tutorial on Bottom Vision Tests (thanks for that, link below) and I can pick the parts up properly (RVR), and then bring up the test screen with Shift+P which changes the display, but it doesn't move the head at all. Presumably I need to manually move the part to the bottom vision camera first? Changing the values (say "17,0")and then pressing enter doesn't do anything, and entering escape brings me back to the tape/tray datagrid where I have to start over again.

I'll update the wiki entry if you need to manually move the part to bottom vision as well since it isn't specified, but just wanted to make sure the problem isn't on my end.

UPDATE: Looking through the (always somewhat mysterious) manual (p.31), I see that SHIFT+P is for LV-26 only ... for LV-27 (QFP, etc.) you can simply enter P. Never would have figured that out if you hadn't brought it to my attention, though. Thanks again.

You can do similar tests for flying/laser vision as well (lv 1), which is described on p.51 of the manual (now that it makes sense to me):

"In teaching mode, move on tape feeder and press 9 (3 for the 2nd head) and pick up component and press F (shift+F for 2nd head). Then the left window displays so input part type # and angle which is usually zero."

Suddenly part definitions seem slightly less painful to get right. Pfew!

oh right, forgot to put a note in that this is for '26' type vision tests. we havent used it for type 27 or type 1

you can also do a partial-assembly test. between shift-p and partial assembly we have saved hours of frustration

we just put that up. try it, its nice!

Are you first manually moving the head over to the bottom vision camera before the test, though? Following the tutorial it turns the camera on, but the head doesn't move. It seems you have to manually move it above the bottom vision as well.

On a different note, I'm just trying to finally get SOT23 placing, and thanks to the vision test I can see that there's an error when I pick up a SOT23 part (which might explain the problems I've had). It seems to be looking for the long side first. It's a completely different issue, though, so once I can experiment with it a bit more I'll post something more conclusive here in the forum. Everyone else I know with this machine except you has problems with SOT23 (blogger, freaklabs).

??? nope. When i press Shift-P it zooms over to the bottom camera. this is for LV 26 type parts. are you not getting that? what version of the software are you running?

[ktownsend]

Nope ... no movement at all. v2.0.13.

[ktownsend]

Hmm ... upgraded to the latest version and it moves now. Makes me wonder what else has changed in the SW???

Using 2.1.3 now, though it isn't clear what the dif is between MDC77xx and MDC77xx7 other than Win7 support ... http://www.mdc-smt.co.jp/99_blank.htm

Hmm, we're still running 2.0.3
Wonder what changed in the last 10 minor revs?

maybe we should upgrade

? no idea. ask isozee?

Just as an update in case anyone with a current machine stumbles across this (a quote from an email I got today from Isono-san at MDC) ....

Shift + I had bug so it was fixed. Also in teaching of PCB data if you press A and rotate rectangle and Escape then was not changed causing a routine was skipped by some reason so it is recovered now and also tape and vib feeder also added this feature.
Also limor san asked to modify software to return head on feeder after Shift+P etc bottom camera test.
Try V2.1.4 uploaded today.

I haven't tested it yet, but apparently the latest version (at your request) should move back now after the Shift+P test.

Update: I just tested it out and it indeed goes back to the start position afte Shift+P or P.

a good addition, i think
